Why is Louisiana the world’s prison capital? Are the residents of the Bayou State more criminal than other people around the world? Is the state’s law enforcement exceptionally skilled at catching bad guys? Or could the inflated prison population be, at least in part, the result of the perverse economic incentives of crony capitalism?

The hidden engine behind the state’s well-oiled prison machine is cold, hard cash. A majority of Louisiana inmates are housed in for-profit facilities, which must be supplied with a constant influx of human beings or a $182 million industry will go bankrupt.

Several homegrown private prison companies command a slice of the market. But in a uniquely Louisiana twist, most prison entrepreneurs are rural sheriffs, who hold tremendous sway in remote parishes like Madison, Avoyelles, East Carroll and Concordia. A good portion of Louisiana law enforcement is financed with dollars legally skimmed off the top of prison operations.

If the inmate count dips, sheriffs bleed money. Their constituents lose jobs. The prison lobby ensures this does not happen by thwarting nearly every reform that could result in fewer people behind bars.

“You have people who are so invested in maintaining the present system — not just the sheriffs, but judges, prosecutors, other people who have links to it,” said Burk Foster, a former professor at the University of Louisiana-Lafayette and an expert on Louisiana prisons. “They don’t want to see the prison system get smaller or the number of people in custody reduced, even though the crime rate is down, because the good old boys are all linked together in the punishment network, which is good for them financially and politically.”
